What you'll learn
In this course students will learn exactly what they need to know for their Biology IGCSE exams. Students will learn about[/center]
1. Describe photosynthesis as the process by which plants synthesise carbohydrates from raw materials using energy from light
2. State the word equation for photosynthesis as: carbon dioxide + water → glucose + oxygen in the presence of light and chlorophyll
3. State that chlorophyll is a green pigment that is found in chloroplasts
4. State that chlorophyll transfers energy from light into energy in chemicals, for the synthesis of carbohydrates
5. Outline the subsequent use and storage of the carbohydrates made in photosynthesis, limited to
(a) starch as an energy store
(b) cellulose to build cell walls
(c) glucose used in respiration to provide energy
(d) sucrose for transport in the phloem
(e) nectar to attract insects for pollination
6. Explain the importance of
(a) nitrate ions for making amino acids
(b) magnesium ions for making chlorophyll
7. Investigate the need for chlorophyll, light and carbon dioxide for photosynthesis, using appropriate controls
8. Investigate and describe the effects of varying light intensity, carbon dioxide concentration and temperature on the rate of photosynthesis
9. Investigate and describe the effect of light and dark conditions on gas exchange in an aquatic plant using hydrogencarbonate indicator solution
10. State the balanced chemical equation for photosynthesis as: 6CO2 + 6H2O → C6H12O6 + 6O2
11. Identify and explain the limiting factors of photosynthesis in different environmental conditions
12. State that most leaves have a large surface area and are thin, and explain how these features are adaptations for photosynthesis
13. Identify in diagrams and images all structures in the leaf of a dicotyledonous plant
14. Explain how the structures listed in 13 adapt leaves for photosynthesis

Description
This Biology course is structured specifically around the latest Cambridge IGCSE and GCE Biology syllabus, ensuring complete and accurate coverage of every objective students need to master for their examinations. Students preparing for AP Biology, IB Biology, or equivalent international curricula will also find this course highly valuable for building a thorough understanding of the theory component of their exams, as the core biological concepts covered are closely aligned across these specifications.
The course focuses onUnit 6: Plant Nutrition, a unit that is consistently well represented across all exam papers and one where students who are properly prepared can score very highly. Every syllabus objective is covered in full, ensuring students have zero gaps and are completely ready for any question this unit throws at them.
Every syllabus objective is covered comprehensively, without overloading you with irrelevant material. The content is precise, focused, and directly aligned with what examiners expect - so you spend your time learning exactly what matters and nothing that does not. Throughout every lesson, real past paper questions are used to show you how this unit is examined, what a full-mark answer looks like, and the common mistakes that cost students marks every single year. You will know not just what to say, but how to say it - and equally importantly, what not to write.
The course builds strongexam technique alongside content knowledge, covering every question type across Papers 1, 2, 3 and 4 - from multiple choice and short answer to structured and extended response questions. Students leave this course knowing exactly how to approach any question on this unit regardless of how it is worded.
Every video lesson comes with adownloadable PDF resource that contains everything you need to know for that specific lesson - definitions, diagrams, key points and exam tips - all written and structured to match exactly what the syllabus requires. There is no need to open a textbook, search for revision guides, or look anything up online. Simply watch the lesson, download скачать the PDF, study from it, and go straight to past papers. Everything you need is right here in one place.
Thepractical component is fully covered in this course. Students are taken through all the investigations they need to know for this unit - investigating the need for chlorophyll, light and carbon dioxide for photosynthesis using appropriate controls, investigating the effects of varying light intensity, carbon dioxide concentration and temperature on the rate of photosynthesis, and investigating gas exchange in aquatic plants using hydrogencarbonate indicator solution. Each experiment is broken down in detail - covering the method, variables, expected results, data interpretation and evaluation - with specific training on how to answer practical questions inPapers 5 and 6 that test experimental skills, data analysis and scientific reasoning under exam conditions.
This course is ideal for students aiming for high achievement and A* grades in Biology examinations.
